You can also embed plots, for example:

# Merge and format data
df <- merge(data_csv, zipcode, by.x='Provider.Zip.Code', by.y='zip') %>% 
  select(-Provider.City, -Provider.State, -Provider.Zip.Code) %>%
  mutate(Average.Covered.Charges   = as.numeric(gsub( "[$,]", "", Average.Covered.Charges)),
         Average.Total.Payments    = as.numeric(gsub( "[$,]", "", Average.Total.Payments)),
         Average.Medicare.Payments = as.numeric(gsub( "[$,]", "", Average.Medicare.Payments)),
         Total.Discharges          = as.numeric(Total.Discharges))
group_by(df, DRG.Definition, state, latitude, longitude) %>% 
  summarise(discharges = sum(Total.Discharges)) %>%
  ggplot(aes(x=state, y=DRG.Definition, size=discharges)) + geom_point()

# Make the map object
require("ggmap")
map <- get_map(location='texas', zoom=6, maptype = "terrain",
             source='google',color='bw')

atx <- get_map(location='austin, texas', zoom=8, maptype = "terrain",
               source='google',color='bw')
ggmap(atx) + 
  geom_point(
    aes(x=longitude, y=latitude,  size=Total.Discharges, 
        alpha=Total.Discharges, color=Average.Total.Payments, position="jitter"),
    data=filter(df, state=="TX", Average.Total.Payments < 40000) , na.rm = T)  + 
  scale_color_gradient(low="yellow", high="red")
